Flood Watch

Redondo Beach, WA

Day 1: 2025-01-15

CATEGORY 3

WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood-related damage. The morning high tide is expected near 20.5 ft.

WHEN
Highest risk from approximately 6:00 AM to 8:00 AM PST.

IMPACTS
Minor flooding in very low-lying coastal areas is possible, but significant property damage is unlikely.

ADDITIONAL DETAILS...

• Barometric pressure at the morning peak (around 1014 hPa) is higher than most severe flood events, reducing the chance of widespread flooding.
• NOAA’s Flood Likelihood is 7.2% for 2025-01-15, which is moderate but still below levels observed in more damaging historical Category 4 or 5 events.
• Winds are generally light and not from the W/NW, further lowering the risk of severe coastal inundation.
• This situation is comparable to past Category 3 events (e.g., 01/06/2025), which had similar tide heights but slightly higher NOAA flood likelihood.


Day 2: 2025-01-16

CATEGORY 3

WHAT
Close to a flood event and worth monitoring. High tides are again near 20.4 ft, but damage is unlikely.

WHEN
Primary period of concern is from about 7:00 AM to 9:00 AM PST.

IMPACTS
Minor inundation of beaches or coastal walkways is possible, particularly around the morning high tide; however, broader property impacts are not expected.

ADDITIONAL DETAILS...

• Barometric pressure remains relatively high (around 1023 hPa in the morning), limiting severe flood potential.
• NOAA’s Flood Likelihood is 4.2% for 2025-01-16, lower than Day 1, suggesting a lesser chance of flooding despite the similar tidal range.
• Historical data indicates that tides above 20 ft should be watched carefully, but high pressure and modest wind speeds reduce flooding risk to Category 3.


Day 3: 2025-01-17

CATEGORY 3

WHAT
Close to a flood event with high tides around 20.2 ft, but still unlikely to cause major issues.

WHEN
Greatest risk window extends from roughly 7:30 AM to 9:30 AM PST.

IMPACTS
Potential for minor roadway or parking lot ponding near the coast, but widespread flooding is not anticipated.

ADDITIONAL DETAILS...

• Barometric pressure is near 1019 hPa, which is not low enough to significantly amplify tidal flooding.
• NOAA’s Flood Likelihood is 2.8%, even lower than the previous two days.
• Despite the relatively high tide height, conditions are comparable to milder historical Category 3 events, with no strong onshore winds and moderate atmospheric pressure.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
